Julia: How to clear console

Question

I am using Julia Studio and would like to know the command for clearing the console of text and memory like imports or variables? Something like matlabs "clc" and "clear" commands.

Solution 1

To clear the console, you can go into the shell and run clear (or cls) from there:

julia> ;
shell> clear

Solution 2

To clear Julia REPL, press Ctrl + L.

Solution 3

As mentioned workspace() provides a fresh Main. One can clear variables (and the screen) with the following:

function clear()
    Base.run(`clear`)
    for var in names(Main)
        try
            eval(parse("$var=0"))
        catch e
        end
    end
    gc()
end

Variable definitions are permanent but can be nulled. To free types and the like wrap them in modules. For more info see the first two questions here.

TERM environment variable not set. failed process: Process(`clear`, ProcessExited(1)) [1]

That's the elegant way to do that!

Nice to clear the screen, but do not free the memory.
